Recommended Practice for the Design of Tubing Installations for Aerospace Fluid Power Systems

2012-08-22
HISTORICAL
ARP994A
This document provides recommended practices for the design of tubing systems that are used for the transmission of liquid and gasses in fluid power systems for aerospace vehicles such as aircraft, missiles and boosters. The primary emphasis is given to recommended practices for line sizing, tube routing, supports and clamping, stress considerations and permissible defects, and provisions for flexure through the use of flexible hoses, coiled tubes, swivel joints, and expansion glands. The sections regarding tubing materials and fitting types are included for reference, but particular recommendations are purposely avoided since their selection is dependent upon the specific requirements of each particular vehicle system and many other factors.

HISTORICAL
ARP994
This document is a compendium of recommended practices for the design of tubing systems for the transmission of liquid and gasses influid power systems for aerospace vehicles such as aircraft, missiles and boosters, and is considered applicable to the design of future space vehicles and other applications using aircraft technology. Primary emphasis is given to recommended practices for line sizing, tube routing, supports and clamping, stress considerations and permissible defects, and provisions for flexure through the use of flexible hoses, coiled tubes, swivel joints, and expansion glands. Fluid power systems are differentiated from the normal aircraft fuel and oil systems and the various fluid systems used for environmental control and air conditioning systems; however, the practices cited herein will in many cases be applicable to these other systems.

CURRENT
AS5586A
This SAE Aerospace Standard (AS) specifies the general requirements for hydraulic system reservoirs that are installed in commercial and military aircraft and helicopters and also in missile hydraulic systems. This document includes design, test (production and qualification) criteria for various types of reservoirs. Appendix A provides information on hydraulic fluid volume requirements and reservoir sizing. This document also provides a basis for the Procurement Specification to completely define individual reservoir requirements.

ARP584B
This SAE Aerospace Recommended Practice (ARP) encompasses design, analysis, fabrication, and installation of pressurized metal tubing used in fluid power systems to provide relative motion. Specific data given are for MIL-T-6845 tubing ranging from 1/4 to 1 in (6.3 to 25 mm) to diameter used in 3000 psi (20.7 MPa) hydraulic or pneumatic system, Military Type I, II, III, or IV hydraulic systems applied to any type of vehicle. For information on design of coiled tube assemblies using Ti-3Al-2.5CWSR tubing, see ARP4146. The flexible configurations of tubing are intended for application to actuators that oscillate about a pivot, to areas of large structural deflection such as reservoirs installation, and to areas of extreme environment where flexible hose could not survive.

ARP4146C
This SAE Aerospace Recommended Practice (ARP) addresses the design, installation, and testing of coiled tube assemblies using Ti-3Al-2.5V cold worked, stress relieved (CWSR) tubing per AMS4945. It specifically details five different configurations of coiled tubing. The configurations detailed herein should be compatible with pressure levels up to 8000 psi (55.2 MPa) upon completion of analysis for the actual stress and life requirement of the intended application. Formal qualification tests are recommended to verify satisfactory installation, clamping, and the life of each unique design. NOTE: For information on design of coiled tube assemblies using CRES steel tubing, see ARP584.

This SAE Aerospace Recommended Practice (ARP) addresses the design, installation, and testing of coiled tube assemblies ranging from 1/4 inch (6.3 mm) to 1.0 inch (25 mm) diameter using CRES tubing per AMS-T-6845, unless otherwise approved by the Procuring Activity. This ARP specifically details three different configurations of coiled tubing. These configurations should be compatible with pressure levels up to 3000 psi (20.7 MPa) upon the completion of the analysis for the actual stress and life requirement of the intended application. However, formal qualification tests are recommended to verify the satisfactory installation, clamping, and the life of each unique design.
